While these leggings are super comfortable and fit well, they are thin. I ordered them because they say fleece lined which to me I expected them to be just that, leggings with an extra fleece lining to make them thicker and warmer in for the winter time. That was my mistake for assuming that's what it meant. These are one thin layer of soft, comfortable fabric, so if you are looking for leggings for regular weather conditions these are great. I love the pocket, it is large enough to keep your phone on your side, but these are definitely not for cold winter weather.
